Leaking injector on my petrol Ford F 250
It is essential to know that the injectors on petrol and diesel engines are distinct, actually, the difference in combustion between these two types of engines makes the injection distinct. The biggest difference lies in the pressure experienced by the injectors, on a petrol engine it will vary between 3.5 bars for indirect injection and 120 bars for indirect injection.
Leaking injector on a petrol Ford F 250: The different leaks
It should be said that injector leaks on a Ford F 250 equipped with a petrol engine are pretty rare. This is resulting from the much lower pressure in the petrol intake systems. Nevertheless, there are two types of leaks:
- Leakage from the top of the injector:
It is conceivable that you have a leak from the top of the injector, this is the portion that is attached to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
At last, you may encounter a leak coming from the lower part of the injector of your car, this one will appear from the junction with the engine and not with the rail as seen previously.
Leaking injector on my diesel Ford F 250
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system produces very high pressure in the engine, as do the injectors. On these models, the pressure is more than 10 times higher than on the direct injection of car petrol engines, reaching 1800 to 2000 bars.
Leaking injector on diesel Ford F 250: The different leaks
In the circumstance of leaking diesel injectors on your Ford F 250, there are three different types of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform as time passes, usually the leak will be at the clamping point. - Injector return leakage:
As its name reveals, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Ford F 250 will be the result of an O-ring or its plastic tip that leaks. - Injector base leak:
This injection leak is one of the most annoying, it is the junction between the engine and the injector nose that leaks at a copper seal, you should find an air noise and a compression loss. - If after verifying you have oil leaking but it does not come from your injectors, we advise you to consult this content page on the existence of oil leaking on your Ford F 250.
Leaking injector on my Ford F 250, how to fix the leak
And to finish, we’re going to take a look at how to fix a leaking injector on your car. Frequently a leak is linked, as we have seen prior to this, to a worn seal caused by the pressures suffered. But think that the pressure in the circuit is enormous, especially on diesel engines. So you will have to take some safety measures:
- Lower the pressure before any work is completed…
- Covering you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Relating to the repair part of your leak, it will regularly be limited to swapping the seals that have failed:
- Find out the source of the leak
- Take apart the injector in question
- Replace the corresponding seal kit
- Reassemble the set up and tighten with a torque wrench in accordance with the manufacturer’s standards.
In all situations, these interventions are not inevitably difficult, but if you have the tiniest uncertainty in the treatment of your injector that leaks on your Ford F 250, we advise you to get closer to your auto technician to avoid any bad manipulation that could severely harm the condition of your Ford F 250.
